The online polishing usually sets a top rod at equal intervals under the transition roller, uses a lever to lift the plate spring, places a graphite block on the plate spring, hangs a counterweight on the lever hanger when tin ash marks and other under-plate marks appear, lifts the graphite block, and polishes the roller. This method has general effect when facing stubborn attachments. The offline polishing is usually used when the transition roller and the annealing furnace roller have large area damage or excessive attachments, causing under-plate quality problems. That is, the roller in a certain area is disassembled piece by piece, polished and polished, and then reinstalled in place. This method is time-consuming, risky and high in cost.

[0041] The embodiments of the present application provide a transition roller polishing device, as shown in Figure 1 and Figure 2 It includes a support 10 and a polishing piece 20.

[0042] The support 10 includes an operating end 11 and a fixed end 12, the operating end 11 and the fixed end 12 are located at both ends of the support 10, wherein the operating end 11 is used for the part for the user to interact with the polishing device, and the fixed end 12 is used for fixing the polishing piece 20;

[0043] The polishing piece 20 is rotationally arranged on the fixed end 12, and the polishing piece 20 has a polishing structure 200, which is used to rub and slide with the dirt on the transition roller and grind the dirt off the transition roller;

[0044] The Vickers hardness of the polishing piece 20 is less than that of the transition roller.

[0045] The transition roller polishing device provided by the embodiment of the application polishes the transition roller by using the polishing piece 20 with a Vickers hardness less than that of the transition roller. The polishing piece 20 can closely contact the transition roller and polish the dirt and stains on the transition roller without scratching the transition roller. Moreover, the polishing device has a simple structure, is easy to operate, has a good polishing effect, can effectively avoid the reduction of the quality of the glass in the production process, thereby avoiding huge losses, and meets the current production operation requirements.

[0046] In application, the operation end 11 is the part for the user to interact with the polishing device. It can be designed in the form of a handle, which is convenient for the operator to hold and apply force. The operation end 11 is designed in accordance with ergonomics to reduce the fatigue of the operator and provide sufficient control force to accurately control the polishing piece 20. The fixed end 12 is used to install and fix the polishing piece 20. It has sufficient strength and stability to withstand the friction and pressure generated during polishing, while ensuring that the polishing piece 20 can rotate smoothly. The fixed end 12 is detachably connected with the polishing piece 20, which is convenient for replacing or adjusting the polishing piece 20, so as to facilitate maintenance and adapt to different sizes or types of transition rollers.

[0047] In application, the polishing piece 20 is designed to be freely rotatable, which enables it to roll along with the rotation of the transition roller when it is in contact with the surface of the transition roller, thereby achieving uniform polishing effect. This design reduces the resistance during polishing and reduces the risk of potential damage to the surface of the transition roller. The polishing structure 200 is the part that directly rubs against the dirt on the transition roller and removes it. The material selection of the polishing structure 200 is crucial, as previously mentioned, its Vickers hardness must be less than that of the transition roller (for example, using brass), to ensure that the transition roller surface is not scratched while effectively removing impurities. In addition, the polishing structure 200 can have a specific texture or shape to enhance its cleaning ability. This feature ensures that the polishing piece 20 will not cause unnecessary wear or damage to the transition roller during operation. By selecting a material with appropriate hardness, the integrity of the transition roller can be protected while maintaining high cleaning efficiency, prolonging its service life.

[0048] In some embodiments, as shown in Figure 1 The fixed end 12 is further provided with a support plate 30, and the polishing piece 20 is rotatably arranged on the support plate 30, and there is a gap between the polishing piece 20 and the fixed end 12. The gap between the polishing piece 20 and the fixed end 12 can effectively reduce the direct contact between them, thereby reducing the wear caused by friction. This not only prolongs the service life of the polishing piece 20, but also reduces the damage that may be caused to the fixed end 12.

[0049] In application, the support plate 30 provides a stable support platform for the polishing piece 20, allowing it to roll freely on the surface of the transition roller. This design ensures that the polishing piece 20 can move smoothly with the rotation of the transition roller, avoiding irregular movement caused by the fixed end 12 restriction, thereby improving the accuracy and uniformity of polishing. Since there is a gap between the polishing piece 20 and the fixed end 12, when the polishing piece 20 rubs against the transition roller, the vibration generated will not be directly transmitted to the fixed end 12 or the support 10, reducing the vibration of the entire device, further improving the quality and stability of polishing.

[0050] In some embodiments, as shown in Figure 1 and Figure 2 , the polishing piece 20 is a semi-circular brass plate, which includes an arc-shaped part 21 and a flat part 22 connected to both ends of the arc-shaped part 21, and the flat part 22 forms the polishing structure 200. The design of the flat part 22 increases the actual contact area with the surface of the transition roller. In some embodiments, the surface of the flat part 22 is a plane. Compared with a purely circular or arc-shaped polishing surface, the flat part 22 can more effectively cover the width of the transition roller, and a larger area can be processed at one time, improving work efficiency. Since the flat part 22 and the arc-shaped part 21 of the brass plate share the pressure and friction during polishing, this helps to evenly distribute wear and prevent local overwear. Therefore, the service life of the entire polishing piece 20 is extended.

[0051] In application, the design of the semi-circular brass plate makes it easier to install and remove. The operator can easily adjust the position and angle of the polishing piece 20 according to the actual situation to adapt to different diameters or types of transition rollers. In addition, the design of the flat part 22 also makes it easier to fine-tune the polishing piece 20 on the support plate 30, ensuring optimal polishing results. The flat part 22 provides additional stability, making the polishing piece 20 more stable during work, reducing the risk of uneven polishing or scratches caused by irregular movement. This design is particularly suitable for situations that require high-precision polishing, such as transition rollers in float glass production lines. The combination of the flat part 22 and the arc-shaped part 21 makes it difficult for debris or dirt generated during polishing to accumulate inside or around the polishing piece 20. The operator can more easily clean these debris, keeping the device clean and ensuring continuous high-efficiency polishing performance.

[0052] In some embodiments, as shown in Figure 1 and Figure 3As shown, a polishing layer 23 is provided on the straight portion 22. The surface of the polishing layer 23 is uneven, and the polishing layer 23 is formed by laying at least one of copper alloy particles, aluminum alloy particles, stainless steel particles, and low carbon steel particles. This helps to increase friction. The uneven surface increases the friction with the surface of the transition roller, allowing the polishing layer 23 to more effectively remove impurities such as tin and oxides. This increased friction helps to improve cleaning efficiency and ensures a cleaner surface on the transition roller. The uneven surface provides more contact points, allowing multiple areas to be treated simultaneously during polishing, improving the uniformity and coverage of polishing. Each particle is equivalent to a miniature polishing tool, working together to achieve a better cleaning effect.

[0053] In some embodiments, such as Figure 4 As shown, the polishing element 20 is a trapezoidal brass plate, with its four sides forming the polishing structure 200. The trapezoidal design gives the brass plate four sides, each of which can be used as a polishing surface. The two non-parallel sides of the trapezoid provide different contact angles, allowing the selection of the most suitable polishing angle based on the surface condition of the transition roller and the distribution of dirt. In other embodiments, such as... Figure 5 As shown, the grinding component 20 is a triangular brass plate, with its three sides forming the grinding structure 200. Designing the grinding component 20 as a trapezoidal or triangular brass plate, and having these shapes form the grinding structure 200, not only improves grinding efficiency and cleaning effect but also enhances the flexibility and durability of the equipment. This design can be selected according to specific production needs and the condition of the transition rollers, ensuring optimal grinding performance and economic benefits. In this way, the transition rollers are better protected, ensuring the normal operation of the float glass production line, reducing the defect rate, and lowering production costs.

[0054] In some embodiments, such as Figure 1 As shown, the transition roller grinding device also includes a fixing bolt 40, a first mounting hole is provided on the support plate 30, and a second mounting hole is provided on the grinding part 20. The fixing bolt 40 passes through the first mounting hole and the second mounting hole to fix the grinding part 20 on the support plate 30.

[0055] The grinding component 20 can rotate around the fixing bolt 40. This ensures that the grinding component 20 can fully contact the surface to be ground by the transition roller.

[0056] In application, the fixing bolt 40 passes through the mounting hole of the support plate 30 and the polishing piece 20, forming a stable rotating shaft. This allows the polishing piece 20 to rotate freely on the surface of the transition roller, ensuring smoothness and consistency during polishing. Since the polishing piece 20 can rotate uniformly around the fixing bolt 40, uneven wear caused by eccentricity is avoided, prolonging the service life of the polishing piece 20. The design of the fixing bolt 40 makes it very convenient to install and remove the polishing piece 20. The operator can quickly replace the worn-out polishing piece 20 without stopping the machine, reducing downtime and improving production efficiency. By loosening or tightening the fixing bolt 40, the position and angle of the polishing piece 20 can be easily adjusted to adapt to different diameters or types of transition rollers, or fine-tuned according to actual needs, ensuring optimal polishing results.

[0057] In some embodiments, the design of the handrail 100 conforms to ergonomic principles, providing a comfortable grip point for the operator. This helps to reduce fatigue caused by long-term operation and improves work efficiency. The handrail 100 provides a stable support point for the operator, allowing them to more easily control the direction and force of the polishing device during polishing, ensuring the accuracy and uniformity of polishing.

[0058] In application, the galvanized pipe surface is smooth, and a non-slip sleeve or texture treatment is added on the galvanized pipe handrail 100 to improve the stability of the grip, preventing the operator from losing control of the polishing device due to slippery hands, thereby ensuring operation safety. Galvanized pipes have good corrosion resistance, especially in humid or chemical-containing working environments, effectively preventing rust and corrosion, prolonging the service life of the handrail 100. Galvanized pipes are usually made of high-strength steel, with good mechanical strength and durability, capable of withstanding large forces without deformation or breaking, ensuring long-term reliability.

[0059] In some embodiments, the support 10 is a square tube with a length of 1m-10m, a wall thickness of 2mm-6mm, and a width less than the width of the U-shaped groove in the transition roller. The wall thickness of 2mm-6mm allows for appropriate selection of wall thickness to ensure sufficient strength while avoiding excessive material usage. The length of 1m-10m allows the longer square tube to cover a larger range of transition rollers, suitable for production lines of different lengths. Selecting the appropriate length according to actual needs can ensure sufficient operating space without being too bulky, affecting operational flexibility.

[0060] In application, the width of the square tube is smaller than the width of the U-shaped groove in the transition roller. It ensures that the square tube can be smoothly inserted into the U-shaped groove of the transition roller, providing stable support. At the same time, the smaller width also makes the support 10 not interfere with the U-shaped groove, reducing the difficulty of installation and adjustment. The simple geometry and standard size of the square tube make it very convenient to install and disassemble. The operator can quickly complete the installation and adjustment without stopping the machine, reducing downtime and improving production efficiency.

[0061] In application, the square tube is a common industrial material with relatively economical price and low manufacturing cost. At the same time, its good mechanical properties and durability ensure a long service life, reducing the replacement and maintenance cost in long-term use. The square tube is easy to cut, weld and drill, with simple manufacturing process, high production efficiency and suitable for mass production. This not only reduces the manufacturing cost, but also shortens the production cycle.

[0062] In some embodiments, the polishing piece 20 is any one of a copper alloy plate, an aluminum alloy plate, a stainless steel plate, or a low-carbon steel plate. The above plate materials are used as the polishing piece 20 because the Vickers hardness of the above plate materials is smaller than that of the transition roller, which will not cause damage to the transition roller during polishing. In a preferred embodiment, the polishing piece 20 is a copper alloy plate: the hardness of copper alloy is usually between HV80 and HV300, and in the embodiment of the present application, the Vickers hardness of the copper alloy plate needs to be lower than that of the transition roller (HV200), i.e. the Vickers hardness of the polishing piece 20 is HV80. The lower hardness makes it not scratch the transition roller, while effectively removing impurities such as tin and oxides. Copper alloy has excellent thermal conductivity, which helps to dissipate heat and prevent damage to the polishing piece 20 or the transition roller during polishing due to overheating. Copper alloy has certain corrosion resistance, especially suitable for use in humid or chemical-containing working environments.

[0063] In application, due to the moderate hardness, the copper alloy plate can remove dirt without damaging the surface of the transition roller, prolonging the service life of the transition roller. The copper alloy plate can provide sufficient friction to effectively remove impurities such as tin and oxides, ensuring the cleanliness of the transition roller surface. Copper alloy has good wear resistance and corrosion resistance, suitable for long-term use, reducing the need for frequent replacement.

[0064] In some embodiments, the total weight of the transition roller polishing device is 20-30 kg. This facilitates one-person operation, which is beneficial for saving labor. In some embodiments, the longest width of the polishing piece 20 is 140-160 mm. When the polishing piece 20 is a semicircular plate, the longest width refers to the diameter of the polishing piece 20; when the polishing piece 20 is a trapezoidal plate, the longest width refers to the longest side of the trapezoid; similarly, when the polishing piece 20 is a triangular plate, the longest width refers to the longest side of the triangle.

[0065] In applications, the weight of 20kg to 30kg is relatively light, which is convenient for operators to carry and move. This is very important for situations that need to adjust the position frequently or switch between different production lines, reducing physical exertion and improving work efficiency. The weight of 20kg to 30kg makes it easy for operators to control the direction and force of the polishing device, especially when working in a narrow space. This helps to improve the accuracy and uniformity of polishing. Within this weight range, one operator can usually complete the carrying and operation of the polishing device, reducing the need for additional manpower and labor costs. The lighter weight makes it easier to carry the polishing device by handcart or other small transportation tools, suitable for flexible scheduling within the factory.

[0066] In the above embodiments, the description of each embodiment has its own focus, and the parts not described or recorded in a certain embodiment can be referred to the relevant description of other embodiments.

[0067] The above-described embodiments are only used to illustrate the technical solutions of the present application, but not limit them; although the foregoing embodiments of the present application have been described in detail, those skilled in the art should understand: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the embodiments of the present application.
